Embodiment 1

[0021] Embodiment 1: A video stream distribution method, including a data source thread and a distribution thread, one data source thread corresponds to N distribution threads, and one distribution thread corresponds to only one data source thread; the specific distribution steps are as follows:

[0022] 1) Create a thread pool, create twice the number of CPU threads used by the server, and divide the threads in the thread pool into data source threads and distribution threads, and establish a corresponding principle, that is, one data source thread corresponds to N distribution threads , a distribution thread corresponds to only one data source thread;

[0023] 2) Create a circular queue for the data source thread. The queue caches 50 frames of data by default. The head of the circular queue points to the newly entered data, and the tail of the circular queue points to the location where the data is obtained;

[0024] 3) Each distribution thread has a pointer to the shared qu...

Abstract

The invention relates to a video stream distributing method and relates to streaming media transmission. The video stream distributing method which is high in distributing performance and balanced in load is characterized in that the method comprises data source threads and distributing threads, one data source thread corresponds to N distributing threads, and one distributing thread corresponds to one data source thread. The video stream distributing method has the advantages that streaming media distributing performance is increased effectively under the same hardware condition, more requesters are supported, the display instantaneity of a requesting end can be well increased, existing hardware resources are fully utilized, and load balance is achieved.

Description

technical field [0001] The invention relates to streaming media transmission, in particular to a method for distributing video streams with high distribution performance and balanced load. Background technique [0002] In the process of developing the streaming media platform, in order to solve the pressure of front-end equipment, such as cameras, IPSAN or DVR and other equipment, the wing board adopts the streaming distribution strategy. Under the condition of the same hardware environment, how to improve the distribution efficiency is a technical problem. There are currently two commonly used methods: [0003] 1. The data source and the distribution process are in the same thread. This method is not efficient in distribution, and the number of copies distributed is not large; [0004] 2. Each distribution object is a thread. This method occupies too many thread resources, and each thread is not fully utilized. Too many threads will also consume resources when switching t...
